To all whom it may concern:

' Be it known that I. SAMUEL Gunrsox. of

Specification of Letters Patent.

the borough of Manhattan. in the city,

county, and State of New York, have invented a new'and useful Glass Dry Cleanser: and I hereby declare that the following is a full. clear, and exact description thereof. which will enable those skilled in the art. to make and use the sam reference being had to the :u-compmiying drawing. and to the characters of reference marked thereon. which form part of this specification.

It is very desirable, for many reasons. to be able to clean glass in windows. mirrors, picture, frames, show cases and similar situations without the use of water or other liquids which are liable to drop or he spattered in the operation, and l have discovered a cleanser by means of which this can read ily, conveniently and rapidly be done, and all dirt, spots and other impurities removed from the surface of the glass.

In the drawing, Figure l is a perspective View of one form of device which may he conveniently prepared for the purpose of carrying out my invention. Fig. l is a lon gitudinal section of Fig. 1. on the line .r .r'.

In this particular device, (2, represents a sheet of paper; (1, one side which may be calendered or be finis'hedsmooth; o. the other side which may be left more open or unca-lendered; I), a thin film of Vaseline,

spread upon the uncalenderedside of the paper, and c, tripoli, or other suitable powder, thereon.

Incarrying out my invention I have sought to obtain a cleansing body by means of which the use of water could be avoided,

and which would be free from any other,

objections- For this purpose'a body is re quired wluch Wlll be free from grease, oily matters, or other substances which Wlll leave a smear, stain, or cloud upon the glass sur- GLASS DRY- CLEANSER.

of vaselineevenly upon sheets of paper, then sprinkle or dust the tripoli on the same. and then out these sheets .into convenient bands or parts for application to the glass. Accordingly, by means of suitable rollers passing overthe surface of the paper, a small quantity of the Vaseline is spread on the paper, and then so much of the tripoli 'is spread or dusted on to the Vaseline treated surface. as will reailily'adhere thereto. but

not in so large a quantity as will permit the tripoli to fall from the paper in the form of dust or powder, but enough to adhere to the prepared paper, and then when a band or portion of such paper is used on the glass, the tripoli is forced into or to the paper i more closely, and is retained there. together with the dirt and impurities thereby'removed from the surface of the glass. In preparing this glass dry cleansing band or strip care must be taken to have the coating of Vaseline spread upon the paper or other backing so thinly and evenly, and of so small a quantity. that when the covering of tripoli is applied thereon, as herein stated, the Vaseline will not pass through such covering upon the glass surface, as otherwise it would itself smear or cloud the glass. it being necessary in order to produce the proper result to the best advantage that there should be sufficient Vaseline to hold the tripoli powder in place, but not more than that.

For using my glass dry cleanser, any suitable body or base may be employed, by means, of which it may be rubbed upon the surface of the glass, and this may also be done by rubbing the paper so prepared on the glass directly by hand.

I do not herein make claim to any mechanical device forsthe purpose of applying my glass dry cleanser, to windows, mirrors,

and other glass surfaces to be cleansed, but

' Y is very satisfactory In applying the vaseline to the paper it is to be applied on the uncalendered side thereof, and care must be taken to apply it in such small quantities that the detergent powder will only be held to the paper thereby, and that there will not be sufficient Vaseline to pass through such powder and smear the glass, etc., which is to be cleansed. The Vaseline not only serves to hold the powder in place, but also seems to render the paper very pliable and satisfactory for the purpose.

his dry cleanser will be found to clean the glass quickly and thoroughly when rubbed over the same, will not scratch or mar the glass surface, or leave a smear or cloudy appearance thereon, and will leave no wet spots or splashes where it is employed, and is very convenient and durable. My experiments have shown that paper of the character mentioned, when used for the backing, gives the most satisfactory results, and while I am not certain of the reason for this, I believe it is because by such paper only a very small quantity of Vaseline is absorbed, and this adheres to the paper, and is suflicient to hold the detergent powder to such backing; while if porous or woven materials are used, a considerably larger quantity of Vaseline is required, some of which enters the pores and interstices in the backing, and this is forced out through the detergent powder when the band is pressed upon the glass to cleanse and polish it, and

thereby the surface of the glass is smeared or clouded, and. not cleansed or polished. The similar or suitable material or backing contemplated is therefore such material or backing as has the qualities of thepap'er mentioned, that is, such as will not take up so much Vaseline as will pass through the detergent powder, and smear or cloud the glass when the band is used. Y

This improvement will be found of great advantage as by means of it the interior of show cases and show windows in which delicate fabrics and manufactures are displayed can readily be cleaned without endangering the same, by splashing of water, etc., and in like manner the glass of mirrors and pictures can be cleaned While in position on walls, etc., without similar danger to wall coverings, hangings, or carpets, etc.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is p 1. A glass dry cleanser consisting of a cleansing surface of tripoli powder, a suitable backing for such surface, in combination with a minute coating of Vaseline spread on such backing, and adapted to hold such tripoli powder to such backing without passing through such powder.

2. A glass dry cleanser consisting of a cleansing surface of slightly detergent powder free from gritty particles adapted to injure glass, a suitable backing for such surface, in combination with an adhesive adapted to hold such powder to the backing without passing through the same.
